This is a pure Go interface to Interactive Brokers IB API. Features include:

  • 100% pure Go (no Java/C calls)
  • Idiomatic design (Go naming conventions, channels, error handling etc)
  • Choice of low-level types or our high-level [Manager](manager.go) types
  • Extensively tested (test coverage via Coveralls, CI via Drone, local [test server](testserver/README.md))
  • Documentation on GoDoc
  • Reflects very up-to-date IB API version

We welcome your involvement and contributions! If you like the project, please click the GitHub "Star" or "[Fork](../../fork)" button. We also invite you to join the [contributor list](../../graphs/contributors) by submitting [pull requests](../../pulls).


  • The code presently supports IB API 971.01 (latest as of March 2014)
  • All reply types (see [ereader.go](ereader.go)) are supported
  • Some request types (see [eclientsocket.go](eclientsocket.go)) require porting


go test requires IB Gateway be running at and providing access to a financial advisor account. Always use a demo or paper trade account, as the tests may modify your account.

The easiest way to start IB Gateway with a financial advisor demo account is to use the test server. Have a look at the [test server instructions](testserver/README.md) for all the details.

By default the tests produce no output. If you'd like to view engine communication logs during test execution, set the IB_ENGINE_DUMP environment variable to any value. For example, IB_ENGINE_DUMP=t go test.

If you fork this project and would like to configure Drone and Coveralls for your fork, our [Drone instructions](drone.md) should be of help.
